B) Humus is the decayed organic material that gives soil its dark brown or black color.
Facts:
1. The Moon has no atmosphere
2. The Moon has quakes
3. The Moon is a dusty ball of rock, measuring 3,476km in diameter
Superstitions :
1. Gazing too long at the full moon will bring out one’s inner lunatic.
2. The waxing of a new moon is the best time for sowing seeds, weddings, childbirth, new projects and travel.
3. It is bad luck to see the new moon, for the first time of the night, through glass or tree branches.
Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?
Answer:
1.02
Explanation:
By the third Kepler's Law for an elliptic orbital, such as the Earth and the Sun:
T² = R³/k
Where T is the period of the rotation (in years), R is the distance between the planet to the star (in au), and k is the constant which depends on the mass of the star. For Earth and Sun, T = 1 year, and R = 1 au, so k = 1.
For HD 10180g, T = 600/365 = 1.64 years, R = 1.4
(1.64)² = (1.4)³/k
k = 2.744/2.6896
k = 1.02
Because k only depends on the mass, we can conclude that the ratio of the star's mass to our sun's mass is the ratio of the k values, so it will be:
1.02/1
1.02

<u>Answer:</u>
<em>The percentage error in the measurement is 2.4%
</em>
<u>Explanation:</u>
The measurement made by the student is 
.
But the actual value of density is 
The formula to calculate percentage error is
percentage error = 
Hence percentage error in this case is given by
<em>Percentage error = 
</em>
<em>= 
</em>
A physical quantities value will be determines by various quantities. If errors are made in measuring any of these quantities there will be error in the measurement of the final physical quantity as well.
Here density of a substance is a derived quantity determined by measuring mass and volume of that substance.<em> If errors are made in mass and volume measurements the density value will also be erroneous.
